Fly Racing Dirt FR5 Boots

The Fly Racing Dirt FR5 Boots are the next step in protection from Fly Racing. The FR5 Boots provide full coverage thanks to the TPU (thermoplastic polyurethane) heel piece which connects lateral and medial TPU pieces, as well as the contoured TPU calf plate. Additionally, they employ a brand new 4-stage high-grip sole design that is ready to race your stiffest competition. Stage one is a perforated plush insole resting above the innovative second stage, an injected midsole with a unique fishbone design which is lightweight yet incredibly strong. The durable mid-sole is then further enhanced by the addition of a rigid in-mold flex reducing steel shank. Stage three is a fishbone foam layer designed to transfer shock and vibration which is then encased in the final stage, an anti-vibration molded traction sole.
